I couldn't find a TED talk from my quick search, but for reference, there is a transcript of a talk at Amherst College [1] that mentions the concept:

Alex Tapscott (at the talk as an Amherst College alumnus, known for being the CEO of a cryptocurrency company and writing a popular book published in 2016 about cryptocurrency): "The FBI started calling Bitcoin prosecution futures, because whenever someone spends it, down the road with enough information they can actually trace it back to who the original spender was, and they were able to reclaim a whole bunch of lost coin."

I searched a bit more to see if an FBI agent or attorney used the term on-the-record, but it looks like the closest source is a New York Times article that quoted lawyers without naming a name [2]: "Hence Bitcoin’s wry new nickname in legal circles: “Prosecution Futures.”
